One issue with aluminum is that it is relatively soft and easily scratched/dented/gouged/galled or otherwise deformed. On a plane sole, should any of these irregularities rise above the otherwise flat surface, there is the possibility of leaving a trace in the wood surface. I found with using the Makita power planer, which has an aluminum sole, I had to check regularly to ensure nothing had gotten stuck or made a mark that transferred to the surface being planed. Not too critical, as this tool is generally made for rough work anyway. But its always annoying when a planer pass makes things worse vice better.

Clarification of aluminium concern
Good afternoon everyone
I am appreciative of input from all fellow woodworkers regarding the use of aluminium.As they say two heads are better than one and apart from that I encourage different ideas and listening to people who have more experience/ skill than myself.
I wish to clarify that the aluminium flat bar is not used in any part of the plane. The metal is only used on the attachment when I need to level the edge of a piece of timber for jointing purposes.
In saying that I will still let forum members know if the aluminium does mark or do anything adverse to the timber after numerous trial uses upon completion of my plane for this challenge.
Regards
Anthony

Ah, I see - I obviously misunderstood exactly how the aluminum was being used. Makes perfect sense as a guide - not much pressure applied, so little risk of jamming something into it. Anyway, looking forward to seeing how your plane progresses - you are certainly wasting no time on #5 biscuits and beer!

I epoxied brass flat bar to the plane's sole and drilled four holes to screw the plate down. Left the head of the screw proud of the brass bar with intention of sanding flat. Well what a mistake. I tried unscrewing the screws but epoxy made that impossible... at least for me.
Then trimmed using an angle grinder but nearly ruined the brass. Gave that idea up. Then tried to grind screws flat with some success but not to my likening.
Any way did what I could and ended up with something that is no way perfect but something I will have to live with. All experience and will know better on another occasion.
Trying to convince myself the plane is wabi sabi- Japanese art of beauty in imperfection. It helps me to accept the error is one cosmetic error rather than a functional error.
Kind regards
Anthony

We have all been there. But if you still want to remove it again, did you try heat? With heat you can break down the epoxy and remove the plate again and try a different way.
Most people use slotted screws for something like that. They grind down so that the slot dissapears.

Thank you
Hello Cklett
Thank you for the advice but I'm a little apprehensive heating the brass plate. My other issue is how to remove the screws given the head of the screw has been filed away.
Regards

Hi Anthony,
The best extractor I’ve ever used for removing chewed out screws is the Grabbit; there are copies available but I doubt they are as strong. They are expensive, but they’ll last you for years.Nothing succeeds like a budgie without a beak.

The Chief's suggestion looks pretty good, but if you don't wish to part with hard earned cash at the moment and if you have an angle grinder, use it with a thin cutting disc to cut a slot in the remains of the screw head, Don't worry about cutting into the brass plate as that is destined for the recycle bin any way, Then you should be able to remove it with a flat head screwdriver. If the head has been mostly filed away still continue, but treat it like a grub screw.

You don't need much heat. A heatgun is sufficient.
The ground screws are a problem, but you already have a few suggestions there.
Alternatively you can also drill them out and fill the holes with a piece of dowel.
On the other hand it is on the bottom of the plane. So at least when lying on the bench no one sees it.

Thank you
Hello Forum members
Many thanks to you all for your empathy and advice. I'll have a shot at trying to remove the plate and screws as per suggestions. Not sure when this will happen but some time soon.
Once again thank you- I appreciated it very much.
Regards
Anthony

Good luck. I forgot to detail and you might already know, but just in case. I understand that when using screws for something like that the holes on the metal should only be bug enough that the shank of the screw fits through. And then don't countersink them. Maximum a tiny chamfer on the hole.
Best to use slotted countersink screws. They will stick out when tightened, but the slot will not be lower than the metal surface. So when grinding off it disappears.
I had good results with very small brass Phillips head screws, but they do leave a tiny dint. For bigger screws that's probably worse.
Young Ye on Youtube does that a lot in his plane builds.
As I said you might already know, but thought I mention it just in case.

Good afternoon Forum members
After much deliberation I have chosen to leave brass plate on the sole of the plane as is because it reflects my mistake and a subsequent learning curve for me.
I have drilled two holes into the body of the plane and epoxied two couplers. The couplers will take the cap screws which will connect the support for the attachment. The same size Allen key is used for the attachment support for jointing as well as tightening the iron from under the plane.
Sounds confusing but hopefully the photographs will be self explanatory.
When the support attachment is not in use, I cover the holes ( that have the coupler) with a brass cover that had a hole drilled though the middlethrough which I epoxied a threaded bolt. The sharp edges of the bolt head was partially sanded to take off the sharp edges.
The threaded bold head is not obtrusive when holding the plane
Regards

Additional details
I forgot to mention in the earlier thread that I had to use a spring washer as the cap screw and nut embedded in the brass cover was not effective to tighten the iron and chip breaker. The use of the spring washer did the trick.
