Blackgates 3 Way Toolpost Casting

[John McCullaParticipant @johnmcculla]

Hi all,

Was considering moving to a three way Toolpost setup on my Warco 250V lathe.

I know Blackgate Engineering sell castings, but does anyone happen to know the dimensions of the different sizes?

I also can’t see an option to buy them off Blackgates website, do you have to ring them up to place an order, or have I missed something?

I agree its a bit archaic the catalogue hasnt even got page no’s and yes it looks like the good old telephone.

I think there is an order form you can download and fill in, or just email them with your order/enquiry.

Buy or just make your own that could be done on the lathe it’s meant for. Scroll down for drawings that could be scaled up or down to then fit whatever lathe you have. https://www.model-engineer.co.uk/860/three-way-toolpost-by-david-lammas/

They give the overall size and tool slot size but I would say you may need to go a bit larger than their largest “Boxford” sizes one. You can give them a call or e-mail and I’m sure they can give you a few more details off the drawing. The PDF of the catalogue gives page numbers.

 

As for costings then for the sake of a bit of sawing making your own based on Pete’s link would be a better option as a piece of round or square cast iron can be had for under £20 delivered compared to almost £100 for the casting once VAT and delivery is added.

Minor thought…. Don’t use cast iron as that is a brittle material and could crack under high loadings. Do it in steel….. All commercially made tooling of this type is steel not iron….

All the best.

I don’t know what grade of iron the Blackgates castings are but SG iron bar is no more expensive than GR17 and acts a lot more like steel. Not hard to machine but can smell a bit due to the sulphur content.
