Nice job on the machine mate
Did you say you got it powder coated over automotive bog?? Local PC said that didn't work after I bogged my parts up and told me I'd have to get it painted instead. If it has worked for you I may have to revisit my plans for some items.…..Live a Quiet Life & Work with your Hands

Yes,
Oils ain't Oils
They would need to be different wouldn't they?....marine applications aren't the same as auto applications.
Also Matty has quite successfully used one under powder coating, more than a few times. And it seems your powder coat guy says the other can't be used under his powder coat process.
From my memory of a good few years ago when I used to do a bit of boat work for a few weeks each year with a friend in Perth, they have different chemical base ingredients.
Last thing he would do is compromise his boat with inferior products.

I thought bog was basically the same resin used in fibreglass glass mixed with a talc filler. Maybe it is the filler that varies? Be interesting to hear from someone with some relevant chemical experience. As I'm just guessing here.

What goes under various names such as bog, Bondo, automotive body filler, etc. are all polyester resin based putties with different compositions of sandable fillers, plasticisers, anti-sag agents etc. added. They are mixed with MEKP to cure and being polyesters smell like the classic fibreglass boat building resins. I'm not aware of polyester resins that can withstand powdercoating temperatures, but maybe such resins do exist.
Epoxy resins can also be used as body fillers, either as pre-mixed putties, or by adding various fillers to laminating resins. Epoxy resins are available in numerous high temperature formulations, some quite safe for powedercoating over.
The above is my understanding of resin fillers, but I'm curious what "high grade marine filler" is available locally to do this job under powdercoating, as having a pre-mixed commercial formulation would be very convenient. I'd like to understand why a marine filler would need to be high temperature resistant.

Is there really a need to ask anything more than "Hey Matty, thanks for sharing your experience, I want to try this, can I ask what one, brand/type filler you are using & is there anything special I need to know when using it". As Peter has already pointed out, this is far from the first machine Matty has had powder coated.
Perhaps I'm just not as excited about the specifics of different fillers
Cheers,
Camo

Matty, thanks for the link. I have not used that Norfill before. It's good to learn that it's safe under powdercoat.

Test Date for Matty's Wadkin LP 438.
About two years after the previous post, I too acquired a Wadkin LP.
Wadkin LP Boring and Recessing Machine.
I wish I'd rediscovered this thread earlier as I'd have liked to have a closer look at the Matty's photos - before they got Photobucketted, but with Waldown instead of in the title, I missed it every time.
Anyways, mine, like Matty's, was originally fitted with pulleys like this:
aLP-10.jpg
However, I believe mine was bought by a customer who wanted a machine independant of a lineshaft, so mine was hurriedly converted to a motorised machine like this:
aLP-12.jpg
I believe this because mine is fully machined to accept lineshaft driven fast and loose pulleys
LP 108.jpg
And even the Wadkin tag for mine specifies the countershaft rpm, but the Test Sheet specifically mentions being tested with an electric motor
LP 410 Test Sheet.jpg Test Sheet for my LP 410 of 1925.
Whereas the Test Sheet for Matty's (which has been made available only this month) makes no mention of a motor.
LP 438 Test.jpg Test Sheet for Matty's LP 438 of 1926.
So Matty's LP was tested at the Wadkin works on 7th July, 1926. My machine, 28 LPs earlier, was tested 10 months earlier on 1st September, 1925. In those intervening months the design of the table was modified to allow it to rotate 45 degrees left or right, for the purpose of making stair stringboards (a feature I don't have).
Later again the LP was further modified by moving the motor to the top. Wallace's LPD 636, of 1934, is configured this way.
