Knocking up the first batch of GRP tins Gel coat on Just got to lay up the chopped strand now, and that'll be the first ones made!!
Decided to have a bit of an experiment, and used some glass twill weave that I'd got just needs a couple of days to go off fully now, and we'll see if I've cocked it up and now have some GRP doorstops
Cool, Depending on how you have positioned your cloth, you might end up with some fairly flexible mouldings. Which may actually be a good thing...... If you offset each layer of woven cloth so that the strands are going in different directions you can effectively adjust the stiffness. Chopped mat is stiff in all directions because of the nature of the strands being all over the place. A more bendy moulding might actually suit this application though. Looking forward to the result. Then you can make up some type 1 tins Nick
Well the plan is, if I can do it with 1 layer of twill, it keeps the thickness down too... But I do appreciate the input cos I'm still learning as I go 8)
Best way to learn is by doing Yeah I would think one layer will be very bendy. BUt you could always add another layer after if you want. The only place the thinness might be an issue is the mounting points. Could be worth adding a couple of patches of mat at the points you need to drill mounting holes. I also reckon you will be ok to pop them out after a day. With those shapes they will probably hold their form ok anyway. Nick
Left them for another 24hrs, as the resin was still a little tacky... cold weather really slows down the full cure time Needs a clean and a polish... need to get my moulds polished up some more, and they'll come out shiny then
Nice job! Crank up the catalyst to 4% in this weather. If you can waft some heat on it to start the cure off that helps to, but don't go mad on the heat or it'll blister. Bet your chuffed Nick
Yeah, well chuffed Just gonna wet sand the moulds a touch and polish them up with some G3 and the mop!! but here is the finished pair of std UK bay tins I'll get on with the dash top next now
The moulds do.. but I'm anal about the finish on things that I sell I gave those a buff with some G10, as they came out very satin/flat
