    Question How to Make this mould for a baseboard?

    Hi guys,


    I'm a complete newbie with routers. I have searched a lot trying to find a bit router to make a specific baseboard with no success.

    Could anyone illuminate me with how to replicate this mould? It looks like a classic roman ogee bit, but it's not exactly the same.

    If you can't find one that matches you can have them made, expensive though. https://www.vexorcwt.com/products/

    Default How to Make this mould for a baseboard?

    Hi Pauloms, and welcome to the forum.

    Is that a regular 55 mm rebate? Perhaps a couple more photos from different angles will help.

    EDIT: Oh, I was looking at the wrong piece of timber. Thats a bit embarrassing. I thought the ruler had a broken edge.

    You might be able to make it up using a couple of different/simpler bit profiles like they did in the 'old days' using molding planes. You might have to make 3 passes with 3 different bits, but at least you end up with the profile you want.

    You will probably be lucky to find a router bit with an exact match to an existing old profile. There will be a number of matters to be considered in matching the profile.

    1. How important is it that the profile matches exactly?
    2. How many metres of profile do you require?
    3. How old is the original piece? Is it still available from stock in local timber yards?
    4. If only small lengths are required, can you reuse some from another room or maybe replace all in one room with something similar?
    5. If it only needs to be similar in profile, it is usually very hard for somebody to notice small variations in profile that are not side by side.
    6. How good are you with hand tools and a combination plane?
    7. What is your budget?

    Because the profile goes down below the highest point of the profile and the low part is not symmetrical (it's angled on one side and round on the other side), it is impossible to copy it exactly with the router sitting flat on the timber and running off a fence or bearing. You can get it close with a V-bit and an ogee, but not the same.

    If you want to match it exactly, you would have to do it on edge in a router table with a custom made bit.

    Too expensive for me... But it would be the best solution.

    How much do you need? If its only a few metres then you could make an exact replica with a scratch stock. You just need a bit of scrap wood for the handle and a piece of thin steel for the blade.

    Here is a link to several videos on youtube, most of them seem to dwell far too much on making the handle. For a one-off I would just use two L shaped pieces of plywood with the blade clamped between them.

    You can rout that with the router inverted in a table and the wood standing or running on its thin edge as said.
    Or You could also just hold the router in a vice upside down, safety first of course.

    I use what ever router bits come close then moulding planes . Or Table saw and moulding planes. That's for enough for a piece of furniture . Not a house worth of lining boards or some huge amount .

    How much do you need to mould ?

    You wouldn't be asking if you had a set of moulding planes , right ?

    Next option is grind cutters for spindle moulder. And you wouldn't be asking as well .

    Next option I do is weld up old file steel or braze HSS onto 1/2 " bright bar and make a router bit .
    And again you wouldnt be asking .

    Last option that may suit you is. Look for old router bits made of HSS. The ones put out before carbide . Some are still made Im sure .I can only see small ones on ebay . You can re grind them if you can find one .

    The router bit shop I used to go to had trays of cheap stuff out front for sale . I grabbed some bits from there thart were some sort of cast bit . not carbide . they can be ground to other shapes . If you cant find anything like that . Then Google scratch stock and do that . Its accurate and works good . Its just a bit of a work out . . Thats not a huge shape so wont be to hard with a scratch stock .



    These sort of things are the type of thing for re grinding but looks like you need bigger and better with a 1/2" shank.
